GRAIN CRUSHER AND DISINTEGRATDR:

. SPECIFICATION forming part of Letters Patent No. 296,838, dated April15, 1884.

Application filed February 16, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, J nssn A. Jones, a citizen of the United States ofAmerica, residing at Raleigh, in the county of ake and State of NorthCarolina, have invented certain new and useful. Improvements in GrainCrushers and Disintegrators, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to improvements in that class of grinding-n iils inwhich the grain is crushed between revolving rollers. My mill isdesigned a d constructed more espeoially for crushing" corn for feed forstock and preparatory for flirt-her reduction into meal for bread, andit is provided with two sets of crushing-rollers, arranged one set abovethe other, and with disintegrating devices consisting of a slotted andribbed diaphragmand a bladed cylinder arranged between the two sets ofrollers.

The invention consists of the crushing-rollers and the disintegratingdevices,constructed,

arranged, and combined as hereinafter fully described and as claimed.

In the drawings, Figures 1. and 2 are end elevations. Fig. 3 is a sideelevation. Fig. 4 is a vertical transverse section. Fig. 5 is a top viewwith the hopper removed and the upper rollers partly broken away. Fig. 6is a transverse section of a diaphragm detached, showing the ribs flat.Fig. 7 is a transverse section of the diaphragm, showing in elevationthe bladed cylinder and the points of the blades extended through theslots between ribs having inclined upper surfaces.

A designates the end plates of the millframe, secured in place by thestay-rods a.

Bis the hopper, located at the top of the machine over the upperrollers.

G C and D D designate, respectively, the upper and lower sets ofcrushing-rollers, mounted in bearings Z) 0, attached to the plates A.The upper rollers may be provided with spiral grooves, as shown, and thetwo rollers of each set are arranged side by side, and the bearings c ofoneroller of each set are adj ustably arranged in guides d, and areconnected with set-screwsf,placed in bearings h,attached to the plates Afor the purpose of adjusting the relative position of the rollers tocrush the grain finer or coarser, as required.

E designates a diaphragm attached to and supported by a bar, It, theends of which are extended through and have bearings in holes in theplates A. This diaphragm is provided with the ribs a, which areseparated from each other by the slots of, and are curved downward andextended under the upper rollers. The ribs may be constructed with fiatupper sur faces, or they may be provided with the in.- clined surfaces c11 for conducting the crushed grain to the slots and preventing it fromlodging on the ribs.

F designates a cylinder located below the diaphragm, and having itsbearings in or attached to the end plates, A, and it is provided with aseries of blades, a fastened upon the cylinder in positionto extendthrough the slots to of the diaphragm, as shown. The bladed cylinder isrevolved at arapid speed by means of a belt driven by any suitablepower, (not shown,) and running over the pulley b onan extended end ofthe cylindenshaft.

G designates a roller mounted in bearings attached to the end plates, A.Both ends of the shaft of this roller are extended beyond theirbearings, and one of the ends is provided with a fixed pulley, b, andthe other end is provided with a fixed cog-wheel, 12 which cog-wheel isarranged between and so as to gear with the cog-wheels c cflwhich gearwith the cog-wheels c c, all mounted on the extended ends of the shaftsof the crushing-rollers. These crushing-rollers are revolved lessrapidly than the bladed cylinder by means of a belt driven by power (notshown) and running over the pulley b Inclined aprons d d are removablyarranged in grooves in the plates A. The inner edges of the aprons d areextended downward over the lower set of rollers, to receive the crusheddisintegrated grain which may be dashed against them by the revolvingblades and conduct it to the lower rollers. The inner edges of theaprons d are extended downward and inward under the lower rollers, toreceive and convey the crushed grain which may fall upon them from thelower rollers to a receptacle. (Not shown.)

Each of the crushing-rollers may be pro vided with a scraper, as shownat d", arranged to remove from the roller the adhering particles of thecrushed grain.

grain, passing through these rollers, falls upon the diaphragm E, and isconducted to the slots a where it comes in contact with and isthoroughly disintegrated by the rapidly-revolving blades a, and, thencedescending, is conducted to and between the lower rollers. These rollersbeing set closer together than the upper rollers, the crushed grain isstill further reduced, and is then deposited in the receptacle (notshown) in condition for feed for stock, or to be still further reducedinto meal for bread. More meal may be produced from the same quantity ofcorn and the meal will be less heated in grinding, and it will be freerfrom sharp particles, and hence superior in quality, and it can beproduced faster and with less wear upon the stones, and hence at lesscost, when it is ground from the crushed and disintegrated grain thanwhen the meal is ground from the whole grain.

I am aware that the method of crushing grain by revolving rollers anddisintegrating the crushed grain by revolving brushes, fans, and otherdevices is not new, and I do not claim such method, rollers, ordisintegrating devices, broadly; but

What I claim as new, and desire to secure by Letters Patent, is-- In amachine for crushing and disintegrating grain, the combination of thetwo sets of 3 5 rollers O O and D D, the slotted and ribbed diaphragm E,and the cylinder F, provided with the blades 66*, extended through theslots of the diaphragm,all constructed and arranged substantially as andfor the purposes described. 0

In testimony whereof I affix my signature in presence of two witnesses.
